T0 CLM whom llt may concern:

Be it known that we, WILLIAM FAIR- Bnornnn CARR and JOHN PUsEY MCLIMANS,citizens of the United States, an'd residents of Coatcsville, in thecounty of Chester and State of Pennsylvania, have invented a new andImproved Furnace, of which the following is a full, clear, and exactdescription.

This invention relates particularly to improvements in means forremoving sla and other foreign substances detached from the metal,glass, or other material manufactured `or under treatment in furnaces,the object being to `provide a means for removing slag and foreignsubstances while the furnace is under operation, thus permitting thefurnace to finish its run, obviating the cooling off to remove depositsof slag and the like, which is the usual practice, and which isdetrimental to the life and run of the furnace, also inj urious to thebrickwork, as brickwork is often drawn out when removing slag in theordinary Way, resulting in the stopping of the run.

By our invention the slag may be removed at any time during the runwithout injury to the furnace-walls.

We will describe a furnace embodying our invention and then point outthe novel features in the appended claims.

Reference is to be had to the accompanying drawings, formingr a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical longitudinal section of a furnace embodying ourinvention. Fig. 2 is a transverse section thereof. Fig. 3 is an end viewof one of the truck slag-pockets employed, and Fig. 4 is a side viewthereof.

Referring to the drawings, 1 designates the furnace, having the doorclosed chargingopenings 2 and having in its end Walls gasfiues 3, whichlead into gas-fines 8, which communicate with checker-chambers 5 in theusual manner. At the sides of the gas-fines are airflues 6, theseair-flues communicating with air-course 7 leading into the furnace.air-lues communicate at the lower end with slag-flues 4. As a means forreceiving and removing slag deposits and the like from lues 4 and 8, weemploy' trucks 9, which are movable into and out of the flues on tracksl0. The truck slag ocket bodies consist of metal, and these fiodies have.a lining ,1l

' Afire-brick or the like.

These The inner ends of the truck-bodies are inclined upward, asindicated at 12, so that the upper edges may pass under ledges 13, andbelow the ledges 1-3 are shelves 14, on which a packing 15 of sand is tobe placed, thus practically preventin any passing of as and air to thelower si es of the truck s ag-pocket's. The side edges are also packedby means of brick 16, which rest upon the side lining-bricks of thetruck slagpockets, and upon the upper sidesA of the brick 16 is packin-sand 17.

It will be note in Fig. 3 that the upper portions of the truckslag-pocket sides pass under ledges 18 in the side walls of the flues.

In the operation the as and air pass through their respective ues intothe furnace, where they mix and are ignited, and

the waste products ass out through the flues at the opposite en theheavy foreign matter falling into a truck slag-pocket and the remainderp assing off through the usual stack. Of course the usual valves will beemployed for directing the air and gas into the furnace from either end.The waste products falling into the truck slag-pockets will become har--dened or form slag, and the loaded trucks may be drawn out throughopenings 19. It will be seen that said openings are partly closed by theouter ends of the trucks; but

sufficient space is left to permit cold air toenter and circulate aroundthe trucks. Thus it will be noted that the furnace may be kept incontinuous operation.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent* 1. The combination with a furnace havingchambers, gas and air lues providing communication between the chambersand furnace, of trucks movable into and out of the chambers, and meansfor sealing the upper portion of the truck-bodies in the chambers.

2. The combination with a furnace having chambers communicating with thefurnace through air and gas lines, the inner ends of the chambers havinledges at the to of trucks having their inner ends incline u ward to enage the to edges of the inner ends with t e under si es of the led es,and ledges below the first-named ledges or supportin a sealing material.

3. T e combination 'with a furnace having chambers communicatingtherewith., of

ICO

wheel-mounted truoks movable into and out of the chambers, the bodies ofthe trucks having a. lining of refractory material, sealingbrickcontacting with the lining-brick when the trucks are in the chambers,and sand on said sealing-b ick to form an auxiliary seal.

4. The com ination with a furnace having flue communication withchambers, the side Walls of the upper portions of the chambers havininwardly-extended ledges, of trucks mova le into and out of the chambersand havin their side walls arranged to pass -under Said ledges andsealing material between said flanges and the truck side walls.

In testimony whereof We have signed our I5 names to this specificationin the presence of two subscribing Witnesses.4
